Just got my car last tuesday, sport line with the 18" Pirelli P7s. We have a ton of ice right now on the roads and they are doing just fine, although I can flick the tail out pretty easy if I try. In the bit of fresh snow we had over the weekend it was just fine. I'm actually not sure if I'm going to mount my set of studded Generals.

Just to clarify, this thread is regarding the OEM tires on the M Sport package, which is different than sport-line. To add to the confusion, the Pirelli Cinturato P7 is a summer performance tire while the Pirelli Cinturato P7 All Season is a different all-season tire.

The wheels are non-staggered, so 225/45 all around (just like on the F30 M-Sport all-seasons). This likely means I don't have the increased top speed limiter (not a big deal as I should never be driving this baby hauler that fast).

Ride is very comfortable (especially for run-flats), but grip is a lacking a bit compared to the performance summer tires I'm used to.

The square setup should reduce understeer vs the staggered. I plan to remove the run-flats once they wear. I'd like get a bit more rubber and fit 235/45s. Plan is to fit Michelin Pilot Super Sports (best tire I have ever owned...transformed my E90 335i) and keep a donut in the boot.

I was so unsatisfied with the P7 All-Seasons that I headed back to the dealer Monday. They corrected the problem and replaced the wheels and tires with the proper staggered wheels and Summer P7s. Oh, what a difference...night and day!

The confidence in cornering I had when test driving has returned. I've also noticed an improvement in braking (as suspected). Understeer has not been a problem. I don't plan to test the handling limits any more extremely than I have so far, so understeer is no longer a concern of mine.

I am happy enough with the Summer P7s that I will not get rid of the runflats. I also don't want to give up cargo space for the donut.

In my opinion, it is better to run Summer tires and get a separate set of winter tires if your climate dictates it. The all-seasons are a compromise in every sense of the word.

I just looked at the prices of the summer Pirelli P7s and the Bridgestone S001 runflats...outrageous! Michelin Pilot Super Sports are much less expensive. The wife and I may have to figure out a way to make things work with the donut. Good thing I have the 128i donut to experiment with.

I ordered my X1 xDrive28i Sport Line during Thanksgiving holidays and just picked it up last Friday. My tires are 225/45R18, Continental ContiProContact SSR Grand Touring All-Season. X1 xDrive28i Sport Line used to have Pirelli Cinturato P7 All Season Run Flat Grand Touring All-Season. Now, it changed to Continental ContiProContact SSR (in Tire Rack, the Original Equipment Tires for X1 xDrive28i Sport Line still point to Pirelli Cinturato P7 All Season).
This is my first BMW and first run flat tires. The driving of Continental ContiProContact SSR tires feels good. I do not feel any bumpy, like other X1 owners observed. I feel even more smooth than non-run flat Goodyear Eagle RSA (on my Inifiniti I30).

Congrats! Did you order M Sport or Sport-line? The Contis are a more expensive tire than the Pirelli all-seasons so I expect them to be better performers. Do you travel to the snow occasionally where you may need the all-seasons?

My X1 is Sport Line, exterior color: glacier silver and interior color: coral red. By default, Sport Line comes with all-season tires. I live in Bay Area (NorCal), rain in winter and no snow. But, I occasionally travel to the snow area for skiing. After seeing my car, all three co-workers like the coral red color and black paint on the side skirts and front & rear bump in Sport Line. In first day drive, one of things I like most is the hydraulic steering. The feel of heavy steering is so good. On the highway, it feels like the car can drive itself on rails. Thanks to the posts of this forum, I made a right decision of ordering a xDrive28i without servotronic.

Interesting, you got the same tires as mine. But, your car is X28i M Sport and my car is X28i Sport Line. I picked up my car two weeks ago. It seems that recently BMW changed tires from Pirelli Cinturato P7 Run Flat to ContiSportContact SSR for both X28i M Sport and Sport Line. How do you feel the ride of the tires? I feel the ride is good.

I drove it from the South Carolina BMW Performance Center to central NJ. It's about 650 miles. Doing mostly highway I thought the ride, as far as tires go, was good. I drove it around town for a little bit they great on dry roads on turns but I have to see when it rains or snows.
